Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation for livestock and poultry houses, in particular to positive pressure ventilation equipment for livestock and poultry houses. Background Art

[0002] Livestock and poultry house ventilation is an important environmental control method, which aims to provide a healthy and comfortable growth environment for livestock and poultry.

[0003] Existing livestock and poultry houses are usually ventilated by using fans to draw outside air into the livestock and poultry houses, and then discharge the air inside the livestock and poultry houses to the outside for air circulation. However, in cold seasons, this method is difficult to maintain the temperature inside the livestock and poultry houses. This air flow will cause the temperature inside the livestock and poultry houses to remain in a relatively cold state, making the livestock in the livestock and poultry houses prone to illness, etc., so the staff need to use other insulation measures to control the temperature. In addition, the air flow in the livestock and poultry houses will make the insulation measures less than ideal. Therefore, we propose a positive pressure ventilation device for livestock and poultry houses. Utility Model Content

Pool 112 and two exhaust trenches 113, the bottom of the preheating air duct 141 passes through the collection pool 11 and extends to the left side of the livestock and poultry house 1, the preheating air duct 141 is arranged inside the exhaust trench 113, and a number of exhaust ports 114 are opened on the wall where the liquid storage tank 112 and the exhaust trench 113 meet. By setting the ventilation and insulation component 13, specifically after the outside air is drawn into the preheating air duct 141, the temperature in the exhaust trench 113 is higher than the temperature outside the house, and it will be preheated by the gas in the exhaust trench 113, and then flow into the air duct 131, and then be discharged from the cavity 132 opened above and below the air duct 131, and evenly distributed in the livestock and poultry house 1, so that the inside of the livestock and poultry house 1 remains warm, avoiding the problem of outside air directly entering the house and causing livestock and poultry to become sick, and no other facilities are needed to control the temperature in the livestock and poultry house 1, saving energy.

By setting the adjusting ring 31, specifically, starting the motor 43 to drive the second gear 44 to rotate slowly, the second gear 44 drives the rotating shaft 41 to rotate through the first gear 42, and the rotating shaft 41 will simultaneously drive the elliptical shafts 33 at both ends to rotate slowly, thereby pushing the adjusting ring 31 upward through the spherical protrusion 32, or moving the adjusting ring 31 downward, to control the size of the opening on the adjusting ring 31. When the opening is reduced, the flow of air is reduced, so that the air can stay in the second preheating air duct 141 for a longer time, thereby increasing the preheating effect of the air.

[0030] A specific application of this embodiment is:

[0031] During use, the excrement in the livestock and poultry house 1 will be discharged into the liquid storage tank 112 through the trough 16 for storage, and decomposed to form ammonia and other malodorous gases. The gases are warmer than the air outside the house, and the exhaust gas will enter the exhaust trench 113 through the exhaust port 114, so that the exhaust trench 113 is filled with warm gas. By starting the trench fan 111, the gas in the exhaust trench 113 can be discharged to the outside of the ground. The temperature difference between the exhaust gas and the fresh air outside the house can be used to preheat the fresh air entering from outside the house. At this time, the positive pressure fan 14 is started to inhale the outside air through the air inlet cover 134 at the front end of the preheating air duct 133, and the gas is transported to the preheating air duct 2 141, and the air flows to the exhaust trench. 113, the temperature in the exhaust trench 113 is higher than the temperature outside the house, and the gas in the exhaust trench 113 is preheated. At the same time, the positive pressure fan 21 is started to suck the preheated gas in the preheating air duct 2 141 through the connecting pipe 2, and the preheated gas is transported to the air duct 131, and then discharged from the cavity 132 opened at the upper and lower ends of the air duct 131, and evenly distributed in the livestock and poultry house 1, so that the interior of the livestock and poultry house 1 remains warm. The negative pressure fan 15 is started to circulate the air in the livestock and poultry house 1 to the outside, which can prevent the outside air from directly entering the livestock and poultry house 1, achieving good ventilation and heat preservation effects. There is no need to use other facilities to control the temperature in the livestock and poultry house 1, saving energy consumption.

[0032] By starting the motor 43 to drive the gear 2 44 to rotate slowly, the gear 2 44 drives the rotating shaft 41 to rotate through the gear 1 42, and the rotating shaft 41 simultaneously drives the elliptical shafts 33 at both ends to rotate slowly. When the protruding position of the elliptical shaft 33 contacts the spherical bump 32, the spherical bump 32 will be pushed upward, and the adjusting ring 31 will move upward in the connecting pipe 2, thereby reducing the opening size on the adjusting ring 31, reducing the flow of air, and allowing the air to stay in the preheating air duct 2 141 for a longer time, thereby increasing the preheating effect of the air. When the protruding position of the elliptical shaft 33 is away from the spherical bump 32, the adjusting ring 31 will move downward by its own gravity, thereby increasing the opening size on the adjusting ring 31, which can increase the air flow rate, thereby quickly ventilating the livestock and poultry house 1, and can be adjusted according to different needs, so as to better control the temperature in the livestock and poultry house 1, which is convenient for the growth of livestock.
